Inconstent line references in `check-shims`

[andyw8]

Minor nit:

Duplicated RBI for ::RubyVM::YJIT::enabled?:
 * https://github.com/sorbet/sorbet/tree/master/rbi/core/ruby_vm.rbi#L804
 * sorbet/rbi/shims/core/ruby_vm.rbi:5:4-5:26

Should we output the second entry as sorbet/rbi/shims/core/ruby_vm.rb#5? I don't think the column numbers are needed.
